Booth sales begin tomorrow in our area at grocery stores and other spots, all listed here. (Or download the official cookie-finder app.) But if you’re traveling between Coeur d’Alene and Spokane, you might notice a curious difference in cost: It turns out Girl Scout cookies are one vice-like thing that costs less on the Spokane side of the state border.

“Each of the 112 local Girl Scout councils has the right to set its own price, based on its needs and knowledge of the local market. Today's prices reflect both the current cost of cookies and the realities of providing Girl Scout activities in an ever-changing economic environment.”

Only Idaho and Hawaii tax the sale of Girl Scout Cookies, and a bill in the Idaho Legislature aims to remove Idaho from that very short list. Earlier this week, the state House passed the bill that would exempt Girl Scout Cookies from the 6 percent sales tax, with a large group of Girl Scouts watching from the gallery. But the bill faces an uphill battle in the Senate, where the top Republican isn’t thrilled about granting tax exemptions to organizations just because they ask for it.

Although prices per box do vary, the $4 price point seems to be pretty standard. About $1 of that cost is for the cookies themselves, with the rest going to Girl Scout programs.

The other council in Idaho, Girl Scouts of Silver Sage, has been the one lobbying for the tax exemption. The price there is $3.75 a box, including the 22 cents for sales tax — meaning those Girl Scouts are getting a lot less from each sale they make. Each box sold around Spokane and Coeur d'Alene raises $2.16 for the council’s programming; in Boise each box only raises $1.69. (The rest of the money goes to cookie program operating costs, the specific troop and awards for the girls.)

Wherever you end up buying them, remember that Girl Scouts warns that cookies for sale online “should not be purchased under any circumstances.” They can’t guarantee the freshness or origin of those cookies and, not least, those sales don’t benefit the girls at all.
